Violent media has often been blamed for severe violent acts. Following recent findings that violence in movies has increased substantially over the last few decades, this research examined whether such increases were related to trends in severe acts of violence. Annual rates of movie violence and gun violence in movies were compared to homicide and aggravated assault rates between the years of 1960 and 2012. Time series analyses found that violent films were negatively, although nonsignificantly, related to homicides and aggravated assaults. These nonsignificant negative relations remained present even after controlling for various extraneous variables. Results suggest that caution is warranted when generalizing violent media research, conducted primarily in laboratories and via questionnaires, to societal trends in violent behavior. 相似文献

Abstract Subjects high and low in test-anxiety were presented with an inferential reasoning task requiring the verification of necessary and unnecessary inferences. The task was performed whilst holding either two or six digits in memory. On the verification task, the performance of high-test-anxious subjects was slower and less accurate than that of the low-test-anxious subjects. In addition, unnecessary inferences took longer to process than necessary inferences for the high-test-anxiety group only. The high-test-anxious subjects studied the memory loads for longer than the low-test-anxious group, but their recognition accuracy did not differ. Findings support Eysenck and Calvo's (Cognition and Emotion, 6, 409–434, 1992) processing efficiency theory. The high-test-anxious group's performance on the sentence verification task was impaired overall, and was particularly impaired when performing the unnecessary inference task. However, we also demonstrated that the high-test-anxious group's performance on a secondary memory task was unimpaired as a result of increased effort. 相似文献

In recent years, substructural approaches to paradoxes have become quite popular. But whatever restrictions on structural rules we may want to enforce, it is highly desirable that such restrictions be accompanied by independent philosophical motivation, not directly related to paradoxes. Indeed, while these recent developments have shed new light on a number of issues pertaining to paradoxes, it seems that we now have even more open questions than before, in particular two very pressing ones: what (independent) motivations do we have (if any) for restrictions on structural rules, and what to make of the plurality of new logics emerging from these restrictions, i.e. how to ‘choose’ among the different options. In this paper, we address these two questions from the perspective of a dialogical conception of logic that we've been advocating in recent years. We will argue that dialogical interpretations of structural rules, that is, as rules determining specific properties of the dialogues in question, provide a conveniently neutral framework to adjudicate between the different substructural proposals that have been made in the literature on paradoxes. 相似文献

AbstractThe authors consider the distasteful possibility that parallelism exists between tactics of warfare and sales management operations. The functions of a salesperson are equated to those of a soldier, and the theories of guerrilla warfare as espoused by people such as Mao Tse-Tung are applied to sales management decision areas. 相似文献

Abstract We identify potential problems in the statistical analysis of social cognition model data, with special emphasis on the theories of reasoned action (TRA) and planned behaviour (TPB). Some statistical guidelines are presented for empirical studies of the TRA and the TPB based upon multiple linear regression and structural equation modelling (SEM). If the model is tested using multiple regression, the assumptions of this technique must be considered and variables transformed if necessary. Adjusted R2 (not R2) should be used as a measure of explained variance and semipartial correlations are useful in assessing each component's unique contribution to explained variance. R2 is not an indicator of model adequacy and residuals should be examined. Expectancy-value variables that are the product of expectancy and value measures represent the interaction term in a multiple regression and should not be used. SEM approaches make explicit the assumptions of unidimensionality of constructs in the TRA/TPB, assumptions that might usefully be challenged by competing models with multidimensional constructs. Finally, statistical power and sample size should be considered for both approaches. Inattention to any of these aspects of analysis threatens the validity of TRA/TPB research. 相似文献

The role of context and timeframe in moderating relationships within the theory of planned behaviour
This study examined the moderating effect of context and timeframe on the predictive ability of Theory of Planned Behaviour (TPB) constructs. Three hundred and eighty-three students completed TPB measures either in a campus bar or a library and were randomly allocated to one of three timeframe conditions: tonight, tomorrow or next week. There was a three-way interaction such that the subjective norms of participants in a bar were more predictive of their intentions to binge drink that night, whereas the subjective norms of participants in a library were less predictive of intentions to binge drink that night. This research provides empirical evidence that ignoring context may result in underestimation of the importance of normative factors in binge drinking. It also suggests that other research utilising the TPB needs to take greater account of the impact of context of data collection, which has been neglected to date. 相似文献

People remember different details about the same events, and when they discuss events they exchange new – and misleading – information. Discussion can change memory, especially when the source of new information is highly credible. But we do not know whether the effects of credibility are based on absolute judgments – judging a source's credibility independently from our own credibility – or relative judgments – judging a source's credibility only in relation to our own credibility. We addressed this question by manipulating subjects' expectations, leading them to believe that they either had the same, higher or lower “visual acuity” than their partner while they watched a movie together. To create ample opportunities for the pairs to mention misleading details to one another, each member unknowingly saw a different version of the movie. The pairs then discussed some of the critical differences, but not others. Later, everyone took an independent recognition test. Subjects' susceptibility to misinformation depended on their own credibility relative to their partner's, supporting the idea that susceptibility to misinformation depends on relative differences in credibility. 相似文献

It has been suggested that quantum particles are genuinelyvague objects (Lowe 1994a). The present work explores thissuggestion in terms of the various metaphysical packages that areavailable for describing such particles. The formal frameworksunderpinning such packages are outlined and issues of identityand reference are considered from this overall perspective. Indoing so we hope to illuminate the diverse ways in whichvagueness can arise in the quantum context. 相似文献
